A Review on Effect of Wavelength Assignment on Passive Optical Networks

In this paper, effect of wavelength assignment on passive optical networks has been reviewed. In WDM networks, each Edge Node (EN) has its own light sources, and optical channels, called light paths, are established by using optical carriers generated from Laser Diodes (LDs) at the source. However, such networks will suffer from the need for complicated wavelength management. While designing WDM system is explored, it considers the physical layer impairments incurred by non-ideal optical transmission media that accumulates along the optical path.
